Aresearcher found a significant relationship between a person's age, x 1, the number of hours a person works per
week, x 2, and the number of accidents, y, the person has per year. the relationship can be represented by the
multiple regression equation r = -3.2 +0.012x 1 +0.23% 2. predict the number of accidents per year (to the nearest
whole number) for a person whose age is 58 and who works 57 hours per week.
tl accidents
a.11 accidents
b.10 accidents
c.12 accidents
d.13 accidents

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

the correct is answer is a 9-sided polygon!

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
